stores a cone

The Cone node specifies a cone which is centred in the local coordinate system
and whose central axis is aligned with the local Y-axis. The
bottomRadius field specifies the radius of the cone's base, and the height field
specifies the height of the cone from the centre of the base to the
apex. By default, the cone has a radius of 1.0 at the bottom and a height of
2.0, with its apex at y = height/2 and its bottom at y = -height/2. Both
bottomRadius and height shall be greater than zero.

The side field specifies whether sides of the cone are created and the bottom
field specifies whether the bottom cap of the cone is created. A value
of TRUE specifies that this part of the cone exists, while a value of FALSE
specifies that this part does not exist (not rendered or eligible for
collision or sensor intersection tests).

When a texture is applied to the sides of the cone, the texture wraps counterclockwise
(from above) starting at the back of the cone. The texture
has a vertical seam at the back in the X=0 plane, from the apex (0, height/2,
0) to the point (0, -height/2, -bottomRadius). For the bottom cap, a
circle is cut out of the texture square centred at (0, -height/2, 0) with dimensions
(2 × bottomRadius) by (2 × bottomRadius). The bottom cap
texture appears right side up when the top of the cone is rotated towards the
-Z-axis. TextureTransform affects the texture coordinates of the
Cone.

The Cone geometry requires outside faces only. When viewed from the inside
the results are undefined.

Where I can, I have put links to Amazon for books that are relevant to
the subject, click on the appropriate country flag to get more details
of the book or to buy it from them.

Covers VRML 2 (but not the upcoming X3D standard). A good introduction to all
VRML2 node types and how to build them.

This book introduces 3D concepts, VRML, Java3D, MPEG4/BIFS, and X3D. It is a very
good introduction to the theory, The writers have an in depth knowledge due to
their involvement in the standards making. This is a good book to help you choose
which 3D open standards to use and to give you a good insight into these standards.
It is probably not for those who want a basic introduction to 3D or for these
who want a step-by-step programming in 3D book.
